Problems solved by technology

[0011] As far as cleaning gutters is concerned, further constraints arise from practical difficulties: accessibility, need for ladders, risk of falling, etc.
Additionally, occupants who cannot directly see the contents of the gutters have no incentive to clean

Embodiment 1

[0061] Example 1: Drainage tank equipped with preforming device

[0062] figure 1 A schematic sectional view of a gutter 1 equipped with a preforming device 10 is shown. The gutter comprises side walls 2 and a bottom as well as a large opening 4 . It is occupied by an elongated porous member 10 pre-shaped to match the side walls of the gutter. This part contains a hole 5 extending longitudinally through the lower part of the block part 10 . Water collected from the opening 4 which has passed through the part 10 can flow freely to the downspout. The geometry of the part 10 is designed to be inserted under the gutter fixing bracket 7 of the roof. This has the advantage that no changes are required to the gutter fixing systems normally used. Brackets may also play a role in holding the part 10 in place.

[0063] This part consists of a mass consisting of rubber granules (approximately 5 mm particles) and a polyurethane binder (consisting of aromatic polyisocyanate, for exam...

Embodiment 2

[0064] Example 2: Pots and trays equipped with pre-forming devices

[0065] figure 2 Schematic sectional view representing a flower pot equipped with a preforming device and its backing tray. The space left between the flower pot and the backing plate produces an annular container 1 suitable for mosquitoes to lay eggs. In this space there has been arranged a pre-shaped ring part 10 adapted to the dimensions of the pot and its tray. The porous mass is pre-moulded in the shape of the pots and trays to occupy the full height of the empty trays so that no water can freely enter.

[0066] Part 10 is composed of rubber granules (particles of about 5 mm) and polyurethane binder (comprising aromatic polyisocyanate, for example issued by the company SNAD with reference to STOBIELAST s131.98), wherein the granules are 1 kg and the binder is 180 g. After mixing, the mixture was poured into chucks and allowed to harden at room temperature for about 24 hours. The part thus obtained ha...

Embodiment 3

[0067] Example 3: Sewage filter equipped with preformed device

[0068] image 3 Schematic cross-sectional view showing a filter equipped with a preformed device. The trap is a concrete tank of rectangular cross-section, which receives water from an upper supply pipe 8 and is provided with a drain 9 near its base. Part 10 is a block of the same rectangular cross-section as the tank to be equipped. The part 10 is supported on corner brackets 13 at about a medium height, so that water is collected in the upper part, filtered through the part 10 and flows towards the drain 9 into the lower part. This handling facilitates insertion and removal of the device. The rubber mass can be reinforced with metal reinforcement members 12 (concrete reinforcement type).

[0069] This device helps prevent leaves and other vegetation from clogging the trap and gutters. It keeps debris from entering the trap (and drain) and it also keeps pests (rats, cockroaches, centipedes, etc.) from leavi...

Abstract

The invention relates to a device for controlling the reproduction of aquatic larvae in a container (1) which may retain stagnant water, said container (1) comprising a wall (2) defining a cavity (3) and an opening (4) and comprising a part (10), The shape of the part (10) is designed to fully or partly conform to the shape of the wall (2) of the cavity and seal the opening, said part is manufactured from a water-permeable and air-permeable porous material containing rubber particles and synthetic adhesive agent. The device made of porous material occupies the opening of the sink, so mosquitoes can no longer freely enter the sink. The invention also relates to methods for operating such devices.

Description

technical field [0001] The present invention relates to the field of accessories for the prevention of insect-borne diseases, and more specifically, devices and methods for reducing the reproduction of aquatic larvae, especially mosquitoes. [0002] The invention relates to a device for controlling the reproduction of aquatic larvae in containers where stagnant water may remain, whereby the insects can no longer enter these tanks. The invention also relates to methods of using such devices. Background technique [0003] Mosquitoes are known to play an extremely important role in human or animal health because, in addition to their role as nuisance biters, they represent the largest vector group of pathogens transmissible to humans. [0004] Mosquitoes are responsible for the transmission of malaria (one of the leading causes of human death, 250 to 600 million people are infected and over a million die each year worldwide) and many viral diseases such as dengue fever, yellow...
